(cl. so'4o) 14 Claims.

'I'his invention consists in an improved maga` zine safety razor inwhich by simple manipulation of a feeding device the user may at anytime present in shaving position a fresh blade from a magazine locatedin the razor head. The razor fis designed to receive a magazine or clipcontaining a supply of blades in which the blades,

.if'desired, may be dispensed forsale to the public.

The blade lmagazine is arranged to be dropped into the head of themagazine instead of having to be pushed in endwise as heretofore, thisbeing a particularly convenient mode of replenishing the blade supplyand requiring little or no mechanical skill on the part of the user.

' With this end in view an improved feature of the inventiongconsi'stsa'safety razor having in its head a guard and an open channel adjacentto the guard, in combination with a magazineshaped to fit freely intothe channel so that itmay be dropped directly in place therein and bepositioned or registered by tting in the channel for supplying bladesdirectly in shaving position above 'the guard. f

Another feature consists in a detachable or removable magazine having afeeding device movably mounted thereon and assembledv with the magazine,that is to say, the feedingdevice is an adjunct of the magazine andremains with it rather than' with the-razor frame. The magazine with orwithout the feeding 'device in some embodiments of the invention may beused as aV dispensing receptacle comprising with its en- -closed bladesan article of commerce.

`Means may be providedfor locating the magazine in place when it hasonce been-"inserted in the channel of the razor 'head and such meansserve to retain the rmagazine in operative position until the supply ofblades contained therein Yhas been-exhausted'. Preferably and as hereinshown 'the locating means may have the further function of lclamping thefeeding device to pre-l f Fig. 3 is a lview of the complete razor andmagazine in longitudinal section;

Fig. 4 is a view in perspective of tlie razor head showing the feedingdevice in retracted position;

Fig. 5 is a view in perspective on an enlarged scale showing the razor,magazine,v feeding device and blade stack in exploded relation: and

Fig. 6 is a view in lperspective of the magazine asA seen from beneath.l The razor illustrated herein comprises a frame consisting of a handlehaving a knurled barrel I0 and enclosing a spindle II threaded at itsupy per end for engagement with themagazine and vent chance oraccidental ejectionof a blade or yother displacement of the parts duringthe shaving operation. y l

TheseA and otherv features of the invention will be best understood andappreciated from the following description of Aa preferred embodimentthereof, selected for purposes of illustration and retained at all timeswith limited `longitudinal movement in the barrel I 0. Rigidly securedto the upper end ofthe barrel is the bottom plate I2 of the head as bestshown in Fig. 5.` This extends transversely with respect to the handleand isinclineddownwardly and forwardly. At itslower edge it merges intoa front wall I3 which extends at substantially right angles to itupwardly and ,/forwardly. The front wall merges in turn into the guardvIll which again extends downwardly and forwardly, being longitudinallyapertured to provide bar portions which determines in part the edgeexposure of the blade and are knurled or corrugated for engagement withthe face'of the user.

The bottom plate I2 is provided centrally .with a deep recess or socketI5 which is pressed into the plate concentrically with the upper end ofthe barrel I0. A pair of shallow spacing ribs I6 are disposedtransversely on the inner surface of the bottom pl'ate, one on eitherside of the socket I5. At each end of the bottom plate is providedv anupturned ear Il and in the rear edge of the bottom plate is provided anupstanding back ange I8, this being located immediately behind 'the`socket I5 and spaced between the ribs I6. The parts above describedconstitute the stationary portions of the safety razor maintaining theirillustrated relationship permanently in the razor. The bottom plate I2,the front wall I-I,V the back flange I8 and the ears I'I provide an'open transverse channel or receptacle in which the magazine may befreely placed by the user. l I

'I'he magazine comprises a rectangular enclosure 20 having a threadedboss 2i projecting below its bottom face where it may t with clear-V apair of projecting stops 22, vthese being lo-4 cated nearthe rear edgeof the magazine and` spaced apart by a somewhat greater distance thanthe ribs I6 of the bottom plate. The top plate 23 of the magazineoverhangs its front wall and is cut off at both ends so as to expose theends of a blade beneath it. A pair of shallow recesses 24 are formed inthe top plate of the magazine adjacent to its ends. At its forward edgethis plate is spaced sufficiently above the front wall of the magazineto permit the passage of a single blade in the outlet slit thusprovided, the slit being located behind and slightly above the guard I4when the magazine is properly located in the channel of the razor. 'I'heend Walls 25 of the magazine are formed to present ribs with inwardlyconverging vertical walls designed to engage bevelled corners of theblades contained in the magazine and so guide successive blades upwardlyto the exit -slit while maintaining their cutting edges out of contactwith the walls of the magazine. The magazine is of such depth as tocontain a stack of ten or twelve blades` and an underlying leaf spring26 which tends at all times to lift the stack and hold the uppermostblade thereof in contact with the inner face of the top plate 23.

The blades 30 herein shown are narrow singleedged blades having acentral perforation, centrally disposed end notches and bevelled cornersadjacent to their cutting edge as already intimated. The illustratedmagazine and blade are designed for co-operative use and it will beunderstood that for blades of different design the shape andconstruction of the magazine may be correspondingly modified, all thepresent invention.

Associated with the magazine is a feed member comprising a rectangularshell of thin sheet metal having a back wall 3| recessed to receive;substantially flush the back ange I8 of the razor, and end walls 32knurled to provide grips for the user and spaced so as to enclose themagazine with longitudinal clearance, that is, to pass freely outsidethe end walls 25 of the magazine. The feeding shell has an open front sothat it may be slipped freely upon the magazine from the rear. Itincludes a top wall -33 having transverse slots which set oif a feed dog3l at each end and these dogs are forked to provide a blade-engagingdetent in each. The body of the top plate corresponds substantially inlength to the short top plate 23 of the magazine and is arranged toslide on the surface of that plate. l'Ihe feed dogs, however, embracethe magazine top plate 23 between them and are deflected downwardly intoor below the plane of that plate so as to engage the ends of theunderlying blade which are exposed beneath it and to advance that. bladein a two-.step operation by engaging rst its end notches and then itsrear corners. The top wall is also provided with a pair of roundedinternal projections 35 which come to rest in the recesses 24 'of themagazine when the, feeding shell is in its fully advanced position andact as yielding catches to retain lit in that position.

The bottom plate 36 of the feeding device is within the scope of by thepressure of 4the-spring and the blades beengagement of the stops 22 andthe slots 31 also prevents accidental disengagement of the feedingdevice from the magazine. to the closed-end slots 31 are provided a pairoi' open-end transverse slots 38 for receiving the spacing ribs I6 ofthe bottom plate. It will be understood that the ribs I6 engage thebottom plate of the magazine through the slots 38 and in this wayprovide clearance for .movement of the bottom plate 36 of thefeedingshell between the magazine and the bottom plate I2 of the razorframe. Finally the bottom plate of the feeding shell is cut-outcentrally at 39 to provide clearance for av threaded boss 2| of themagazine.

Assuming that the razor contains a blade in shaving position, as shownin Figs. 1 and 4, and that the user desires to replace that blade with afresh blade from the magazine: 'I'he active blade 30 will be positionedfor shaving by the feed dogs 34 with its edge above the guard Il and thedogs occupying the two end notches of the blade with the feeding shellin its forwardposition, as shown in Fig. 1. It may be assumed also thatthe spindle I I has been turned to clamp all the parts againstdisplacement in this operative relationship. The operator now mayslightly loosen the spindle II and slip the feed device rearwardly intothe position shown in Fig. 2. In Y this movement the feed dogs 34 leavethe end notches of the blade and move back to engage its rear corners,the blade being held frictlonally in this position during their-reversemovement neath it against the top plate 23 ofv the magazine. The feedshell is then moved forwardly whereupon the used blade is advanced byits rear corners forwardly and completely ejected from the razor. Thenext blade in the stack is immediately moved upwardly into contact withthe top plate of the magazine. 'I'he feeding shell is again movedrearwardly and in this movement the feed dogs drop into the end slots ofthe blade now uppermost in the stack, as shown in Fig. 4. A nal forwardmovement of the y feeding shell advances thisblade by its end providedwith a pair of transverse internal slotsVv 31 shaped to receive Vwithvclearancewthe spaced stops 22 on the bottom plate of the magazine. Thefeeding shell isnaturallv resilient so that in assembling the parts'thebottom plate 36 may be sprung over the stops 22, -thereafter relativetransverse movement of the feeding shell and the magazine 20 beinglimited by movement of the stops 22 in the slots 31. This interlockingnotches into shaving position, as shown in Fig. l, where it may beclamped by turning the spindle; Il and is then ready for use.

It will be seen that the entire operation of replacing one blade foranother involves two com plete reciprocations of the feeding device andthat the old blade is completely ejected from the razor before a newblade is advanced from its completely guarded position in the magazine.

A fresh blade may be advanced into operative position at any time beforeor during the shaving operation, that is, if the user. finds a blade tobe unsatisfactory while shaving he has only to loosen the spindle,reciprocate the feeding device twice and then turn the spindle to clampthe new blade in shaving position. Blades may be successively replacedas long as the supply holds out and then the empty magazine 'may bediscarded and' replaced by a full one.

The feeding device is movably retained on the magazine by the f reetravel of the projections 22 in the closed-end ,slots 31 but as alreadyexplained the bottoni plate of the feeding device may be sprungsufficiently to disengage these projections, if desired. The internalprojections 35 of the feeding device snap into vthe recesses 24 of themagazine when the feeding device is advanced into' its forward positionand serve as spring catches to retain it in that position but are read-Adjacent .gage the bottom of the magazine.

ily disengageablefby the user when it is desired to operate the feedingdevice. When assembled in thechannel of the rezor head the solidportions of the bottom plate 36 of the feeding device move transverselyin the bottom of the channel in the space provided by the ribs I6 whichen- When the spindle l l, however, is screwed up ltightly the bottom ofthe magazine is bowed into frictional clamping engagement with theportions of the plate 36 on either side of the aperture 39 thuspreventing accidental movement of the feeding device.

If desired, the recesses 2.4 in the top plate 23 of the magazine may beprojected through into the interior of the plate so as to form stopswhich will act positively to prevent rearward movement of any blade thathas been moved forwardly into shaving position. This is a feature whichis covered in the co-pending patent application of the applicant, JosephMuros, Serial Number 408,945, filed August 30, 1941.
